I can't seem to find the answer to this and I feel like I have read the entire internet

This is my first real month of temping, last time I hit it right on and it worked, so I don't know when I should expect my period this time. This morning, my temp was back down today after 10 days of being high. Obviously it could be a fluke, but since I won't really be here tomorrow or Friday, I figure I could ask.
Do temps go back down and then you get your period right away? My chart is linked in my sig if you want to take a look.
thanks in advance!!! :-D
